Thus the device ma be shi ed in knock down and 199 er is level and there will be no sloppage or spillage by reason of cockingbf'the vessel due to unequal expansion, e 1 v The upper end of the tubular container 30 is flared upwardly and outwardly as at 33 and forms a flared cylindrical mouth for pouring purposes which being a part of the extending edge or lip itfrom dripping and will, therefore, pour clear and free.

The vessel, therefore, is well adapted to pour as well as cooksoups, gravies and the like. Theouteredge of this flared portion is turned downwardly andinwardly as at 34 and serves to form a seat or groove toreceive the outwardly and upwardly projecting end 21 of the shell 10 and lock the same therein. All available space between said shells 10 and 30 not otherwise occupied as hereinafter specified, is filled with mineral wool which serves as an electrical and thermal insulator- In the cooking compartment thus formed, there may be positioned a plurality of vessels such as indicated at 35, each of which is pro vided with a beaded edge36. These vessels as shown clearly in Fig. 2, are adapted to be supportedin superposed relation within the cooking chamberpor may be supported in roaster forming association.

The vessel supporting framework as shown clearly in Figs. 2, 3 and 4, consists of a pair of U-shaped strap members'having their base portions 37 connected togetherat 38 and having their free ends or arms 39 extending in i the same direction, thus forming a stand.

The ends or arms are suitably notched as at 139 and the tongues 40 formed by said notch project inwardly and are adapted to under-lie the beaded edge of the vessel 35 and thus support said vessel in suspended relationship. In Fig. 2 but. the lower vessel is shown supported in suspended relationship, the inter mediate vessel being shown in an inverted position and resting upon the lowermost vessel.

If itis desired, however, the intermediate vessel 35 may be inverted and positioned so that its bead 36 ispositioned above the uppermost supporting tongues 40.' In order to position a vessel in the framework thus described, the framework is placed astraddle or over the vessel and the vessel elevated until the bead passes over the resilient tongues and is retained thereby.

In order to readily removethe vessels from the cooking compartment theframe previousshown in detail. A supporting plate 50 is herein shown ofsheet metal and is provided with a plurality of radially positioned perforations in the' form of a pair'of radially arranged spaced offsets 5l 'adjacentwhich is an'inturned' lateral portion.or 'tongue 52.

Said offsets 51 'are'adapted to sli'dably receive one end 52 of-a spring supporting foot. Thesliding and frictional "movement of the tongue 53 is limited by the abutment'forming tongue 52. The spring portion 53 includes an intermediate and'spacmg portion 54 with an in'tu'r'ned' end 55. When the'plate 50 is positioned adjacent the bottom 31 and the spring portions 55 and 54 engage the bottom or base portion '16 and the'shell l0 and the junction of the intermediate andend portions 54 and 55 respectivelybear against the shell 10, and thus the plate 50 is centered and maintained'in yielding engage'ment'with the bot tom 31, and furthermore is centered'with respect thereto, since a plurality of said spacing and yielding supports are provided and are arranged in spaced relationfo'r' such purpose.

The plate 50 is also provided with a punchedportion 56 which has an angular portion 57 adaptedto lie substantially parallel to the plate portion 50. are so arranged that they extend beneath an insulation'plate 58 and support the same, said insulation plate being maintained in relatively rigid relation with respect to sidewise movement'with reference to plate 50 by the connecting portions 56, and is spacedrelation by the shouldering thereof. 7

The insulation plate 58 supports a heating element 59 in the chamber or space formed between plate 50 and said insulation "plate 58.

Saidelectrical heating element, which may be of any des red form so long as is satisfactory for operation, includes a'terminal i159 Said portions 57 supported by the insulation "plate and said terminal is in electrical connection with a relatively yielding strap connection 60, in turn connected to the terminal 14. I

The body 10 includes a pairof embossments 61 having central'opening's diametrically po sitioned' with respect to each other.

shaped handle or bailjj62'has inturned ends 63 receivable by the openings in the embossmen-ts 61. "Thefarrangement'of' the bailis such that the intermediat'e or' central portion 64' is always maintained in spaced relation from the shell 10, the inclined connecting portions 62 engaging the shell intermediate their ends.

In Fig. 8 a modified form of the invention is illustrated and in this form of the inven tion there is shown a griddle. The general construction of this device is substantially the same as that hereinbefore described, except that the Width or height of the shells are materially reduced. In fact the inner shell has substantially no cylindrical portion wha soever, and furthermore the base 131 is connected directly to the outwardly and upward ly inclined flared portion 133. This forms a skillet in which gravies can be made and the like and readily poured without spillage or drippage since the same type of mouth as previously described is formed by the flared mouth, the outer edge thereof being turned downwardly and inwardly to overlie the outer wall. In this form of the invention the bail 62 has its ends 63 receivable by the perforated embossments 61, said bail being formed to position the handle 64 away from the outer wall 110. Wall 110 has the seam 11 and is retained in position by the inturned continuation of flared portion 133 and by flange 15 of the bottom. Said wall supports the terminal guard 13 beneath which is mounted the handle 12 for pouring purposes and for protecting the terminal guard. The bottom supports the legs 18.

Thus the several parts are arranged for use in both the lireless cooker or the griddle cooker. The interior construction of the griddle is a duplicate of that shown in F 2 or may be otherwise formed.

In Fig. 2 it will be noted that the diameter of the heating chamber is greater than the diameter of the heating element 59. lVith this construction the heat passes upwardly through the bottom and tends to centralize and pass upwardly in a central column if water, soup or the like is being heated in the cooker. This upwardly directed central column of heat produces an outer enveloping downwardly directed cooler column which tends to pass laterally along the bottom 32 and upwardly into the central column after it is heated. By the foregoing arrangement it is possible to obtain in the center of the cooker temperatures from to 150 degrees higher than that immediately adjacent the annular wall of the cooking chamber. The foregoing arrangement, therefore, permits the reduction of the amount of insulation material required between the two walls form ing the sides of the cooker and still retain an efiiciency equivalent to thicker walls, in other words the air or liquid being heated in the cooker forms a partial insulator adjacent the inner wall of the cooking chamber. The stand or support shown in Figs. 8 and 4 is shown positioned in Fig. 2 and as illustrated therein, the same supports the vessels in centralized position in the cooker and in the path of the greatest heat, to wit, that of the central column.
